The '''PD-14''' (earlier PS-14) is a next generation [[turbofan]] engine being developed by [[Aviadvigatel]] to become one of the alternative power plants for the [[MS-21]] twin-jet passenger aircraft. The PD-14 was announced in early 2010 with its development cost estimated at [[Russian ruble|RUB]] 35 billion (US$1.1 billion). The company expects to start the certification procedure for the PD-14 in 2012.<ref>[http://www.avid.ru/eng/pr/news/974/ In 2011 Aviadvigatel OJSC will develop PD-14 engine demonstrator]</ref>

The design has many similarities with the [[CFM International LEAP-X]], such as fan diameter and number of low-pressure (LP) and high-pressure (HP) [[Axial compressor|compressor stages]] as well as the same HP turbine. Only the LP turbine has seven stages on the Leap-X, whereas the PD-14 has only four stages (five stages on the PD-14M).<ref name=take >[http://en.take-off.ru/news/102-feb2011/561-pd-14-11-2010 PD-14: core engine tests launched] Take-off</ref>
 
   
 
The PD-14 turbofan family is planned to be expanded with the [[geared turbofan]] PD-18R, with a thrust of 18,000 to 20,000&nbsp;kg. Applications are expected in heavy passenger and transport aircraft like the Ilyushin Il-96-300/400T.<ref>[http://www.allbusiness.com/government/government-bodies-offices/15627238-1.html Interfax Russia: Aviation PD-18R jet engine to become most powerful in PD-14 turbofan family] Allbusiness</ref><ref>[http://www.avid.ru/upload/pages/7234/IB_22A_ENGLISH_gorizont_ECRAN.pdf PERM Aircraft Engines: Interview] PDF, page 11</ref>
